Police are looking for burglars who stole copper pipes from a pair of unoccupied Colchester homes.

A break-in was reported Tuesday in a vacant house on Buckley Hill Road, and about 500 feet of copper pipe was taken from the home’s basement, police said. The burglary took place at some point in the previous week.

A home on Parum Road was broken into sometime in the past three weeks, and 500 feet of copper pipe was removed from that house as well, police said. The burglary was reported Wednesday.
